Targeted protein degradation (TPD) is an emerging therapeutic strategy with the potential of targeting undruggable pathogenic proteins. After the first proof‐of‐concept proteolysis‐targeting chimeric (PROTAC) molecule was reported, the TPD field has entered a new era. In addition to PROTAC, numerous novel TPD strategies have emerged to expand the degradation landscape. However, their physicochemical...
The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR‐associated protein 9 (Cas9) system offers great opportunities for the treatment of numerous diseases by precise modification of the genome. The functional unit of the system is represented by Cas9/sgRNA ribonucleoproteins (RNP), which mediate sequence‐specific cleavage of DNA. For therapeutic applications, efficient and...
Transition metal‐based nitrogen‐doped carbon (M‐Nx‐C) is considered as a promising catalyst for the oxygen reduction reaction (ORR) in clean energy storage and conversion devices. Herein, ZnCo dual‐atomic sites are incorporated in hierarchical N‐doped carbon (HNC), with 1D nanotubes wrapped in 2D nanosheets structure (termed as 1D@2D ZnCo‐HNC), via a one‐step bio‐inspired pyrolysis. The feeding ratio...
The clustered regularly interspaced short palindromic repeats (CRISPR)‐associated protein 9 (CRISPR/Cas9) is an efficient and precise gene‐editing technology that offers a versatile solution for establishing treatments directed at genetic diseases. Currently, CRISPR/Cas9 delivery into cells relies primarily on viral vectors, which suffer from limitations in packaging capacity and safety concerns....
To deal with the ever‐growing toxic benzene‐derived compounds in the water system, extensive efforts have been dedicated for catalytic degradation of pollutants. However, the activities and efficiencies of the transition metal‐based nanoparticles or single‐atom sites are still ambiguous in Fenton‐like reactions. Herein, to compare the Fenton‐like catalytic efficiencies of the nanoparticles and single...
Electrical contacts often dominate charge transport properties at the nanoscale because of considerable differences in nanoelectronic device interfaces arising from unique geometric and electrostatic features. Transistors with a tunable Schottky barrier between the metal and semiconductor interface might simplify circuit design. Here, germanium nanowire (Ge NW) transistors with Cu3Ge as source/drain...
Ag2S quantum dots (QDs) are well‐known near‐infrared fluorophores and have attracted great interest in biomedical labeling and imaging in the past years. However, their photoluminescence efficiency is hard to compete with Cd‐, Pb‐based QDs. The high Ag+ mobility in Ag2S crystal, which causes plenty of cation deficiency and crystal defects, may be responsible mainly for the low photoluminescence quantum...
Photodynamic therapy (PDT) typically involves oxygen (O2) consumption and therefore suffers from greatly limited anticancer therapeutic efficacy in tumor hypoxia. Here, it is reported for the first time that amine‐terminated, PAMAM dendrimer‐encapsulated gold nanoclusters (AuNCs‐NH2) can produce O2 for PDT via their intrinsic catalase‐like activity. The AuNCs‐NH2 not only show optimum H2O2 consumption...
The Forming phenomenon is observed via in situ transmission electron microscopy in the Ag/Ta2O5/Pt system. The device is switched to a low‐resistance state as the dual filament is connected to the electrodes. The results of energy dispersive spectrometer and electron energy loss spectroscopy analyses demonstrate that the filament is composed by a stack of oxygen vacancies and Ag metal.
Despite nanoparticulate platinum (nano‐Pt) has been validated to be acting as a platinum‐based prodrug for anticancer therapy, the key factor in controlling its cytotoxicity remains to be clarified. In this study, it is found that the corrosion susceptibility of nano‐Pt can be triggered by inducing the oxidization of superficial Pt atoms, which can kill both cisplatin‐sensitive/resistance cancer cells...
Rapid and sensitive detections of a variety of surface and intracellular proteins, nucleic acids, and other cellular biomarkers are important to elucidating biological signaling pathways and to devising disease diagnostics and therapeutics. Here, sensitive imaging and detection of cellular proteins on fluorescence‐enhancing, nanostructured plasmonic gold (pGold) chips is presented. Imaging of fluorescently...
